BACKGROUND OF THE INVENTION Field of the Present Disclosure

The invention relates to a system of substantially reducing bacteria, yeast, mold, food borne illness causing organisms and other contaminants in food and on food surfaces, primarily fresh produce, seafood, poultry, beverages, food preparations and food based cosmetic applications, while simultaneously extending shelf life, reducing spoilage, bacteria and mold growth by applying an antimicrobial, antioxidant solution made from all natural compounds to the food surface, the ingredient deck of a prepared food or a food-grade cosmetic or oral care product. The system is applied via a liquid solution or a biodegradable wipe treated with the solution. The wipes do not require rinsing. The system may also be applied via solid form such as a powder or tablet. The powder or tablet may be made with effervescent ingredients and may dissolve readily in water or other liquid, including but not limited to the natural moisture of the food substance. The powder may be mixed directly into food as a natural additive if there is sufficient moisture content to distribute the powder effectively throughout. The powder may also be reconstituted and applied as a liquid soak, dip or spray to the surface of foods as a sanitizer or incorporated into a recipe to extend shelf life.

Food borne illnesses are an increasing concern in homes across the country. These illnesses are present in part because the foods being sold at grocery stores are grown in organic soil and manure and treated with pesticides and chemicals, then are covered with non-water soluble wax, which can make foods dangerous to consumers upon ingestion. Additionally, these illnesses are sometimes spread when food is not preserved, washed or stored properly, causing the microorganisms, bacteria, dirt, or other particles naturally found in or on the food to be ingested. While consumers are generally aware of the risks of food borne illnesses, they nonetheless fail or are unable to effectively remove the chemicals and bacteria that is the cause.

Waste of fresh foods is one of the leading causes of methane emissions in landfills. According to the U.S. Department of Agriculture, Fresh fruits and vegetables accounted for nearly 20 percent of consumer and foodservice losses. Methane gas from fresh fruit and vegetables is considered 21 times more harmful than carbon dioxide. The environmental impact of this waste affects the global economy.

Most consumers simply wash foods with plain water, however this method generally fails to effectively bring harmful chemicals and bacteria to a safe level for human consumption. Furthermore, water is generally ineffective at removing protective wax from fruits and/or vegetables. Other food wash solutions with chemical compounds are also available. These chemicals are often harsh smelling, turbid, and leave a residue that affects the taste of the food or unsafe if ingested. Solutions are available that are effective in reducing bacteria and pesticide content, and that do not leave a chemical residue; however these washes are generally a disinviting color and are accompanied by a bad taste, both of which discourage usage. Often, their efficacy in food service or manufacturing/processing is limited and may be dangerous. Some are made of chemicals potentially linked to cancer, hyperactivity and other harmful side effects. Some do not allow manufacturers to reach the shelf life they are seeking, while controlling microorganism growth adequately.

As food surface sanitizing product, there is a very strong demand in the organic produce industry to identify safe, effective alternatives to the widespread use of chlorine as a microbial control. Likewise, the food industry is actively seeking all natural, effective products for their customers who are asking for natural, non-allergenic treatment of food.

A powerful, safe, concentrated, quick and evenly dissolving powder and tablet solution eliminates the need to transport water, which is costly and often inefficient, while adding additional stability and shelf life. Additionally, the end user can use the products in an infinite number of varying concentrations to meet their specific needs.

It is therefore desirable for an organic food wash solution that is substantially odorless, colorless, tasteless and safe, and which can be easily produced at low cost and effort, and which may be used on fresh produce, seafood, poultry, legumes, nuts and other raw ingredients prone to microorganisms, yeast or mold.

BRIEF SUMMARY OF THE INVENTION

The primary objective of this invention is to provide an all-natural solution that is easily produced without resort to dangerous or artificial chemicals or heat, and which can remove dirt, pesticides, chemicals and odors, and which can reduce oxidation and spoilage of fresh food, without leaving a residual chemical taste or smell.

Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the presently described apparatus and method of its use.
